How to I make a sticky block in 2.0?

See Block settings. Using the edit icon in the block heading, go to the configuration page. Look for the "Where this block appears" group and "Display on page types". Depending upon your current context and permissions, you will see different options. One maybe "All pages" or "Any type of course main page", and others.

Where did that block come from? I do not want it!

Your site administrator or some one with more permissions than you decided that block should be there. It is possible to force a block to appear on other pages. For example, a site administrator my force a HTML block on every main course page and determine where it will be, so they may put site messages there.
